Description

FIELD OF THE INVENTION

The present invention relates to a board device, and more particularly to the board device of a single board computer.

BACKGROUND OF THE INVENTION

1. Description of the Related Art

With reference to FIG. 1 for a conventional single board computer (SBC), the single board computer includes: a cooling module having a cooling base with four locking members for locking the cooling base onto a baseboard; and a small outline dual in-line memory module (SO-DIMM) disposed on the baseboard and adjacent to the cooling module. The small outline dual in-line memory module, usually abbreviated as SO-DIMM or SODIMM, is a computer memory with integrated circuits. The SO-DIMM is similar to DIMM, but its volume is smaller and approximately equal to half of the size of the regular DIMM.
